Metal Sleeve Custom Black Forged Bushing Shoulder Replacement Iron Sleeve Set

Metal sleeve is a nut used instead of a turnbuckle when high strength rods are required. It is used to a couple of rods and provides some degree of length adjustment. It is stronger than the corresponding connecting rod of the same materials. It is produced from hexagonal or round bars (usually stainless steel). It is given a plain finish. Ever Hardware provides custom-made fasteners and customizable packaging.
A turnbuckle, stretching screw, or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread. The tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye-bolts or attached cables.
Turnbuckles are most commonly used in applications which require a great deal of tension; they can range in mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent metal sleeve rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
